The STM32WL55CCU6 long-range wireless and ultra-low-power devices embed a powerful and ultra-low-power LPWAN-compliant radio solution, enabling the following modulations: LoRa®, (G)FSK, (G)MSK, and BPSK.
STM32WL55CCU6 256-Kbyte flash memory, 64-Kbyte SRAM
For more information about the examples, see the README.md file in the examples directory.
Note that when using UART to view the log, the baud rate is 9600.
Refer to the STM32CubeMX resource pack for more example. It is usually under path C:\Users\user\STM32Cube\Repository\STM32Cube_FW_WL_V1.x.0\Projects
├─1_led : Create simple projects
├─2_jlink_rtt_print : Used only to test jlink printing
├─3_sdcard : Test TF card screen
├─4_oled : Test oled screen
├─5_RF_test : This example is AT Slave and is only used for RF testing
├─6_SubGHz_TXRX : Transceiver test using Lora modulation
├─DeepSleep : Test board sleep power consumption
├─PingPong : Port CubeMX package SubGHz_Phy_PingPong program
The factory firmware in T3_STM32_Firmware\xxx.hex is generated using examples\6_SubGHz_TXRX, the only difference between them is transceiver and frequency.
